Mr. F. P. Pascoe on some new Antkribidce. 327 



Chermes Lands evidently approaches the ordinary Aphides in 

 its conditions of reproduction, except that the viviparous indivi- 

 duals, as also in Phylloxera, are replaced by egg-laying females, 

 and that male individuals are entirely wanting (at least, as a 

 general rule).

XXXIV. — On some new Antkribidce. 

 By Francis P. Pascoe, F.L.S. &c. 



In common with many other families of Coleoptera, the Anthri- 

 bidse have received very little attention from entomologists. 

 This is, perhaps, partly owing to their being scattered in small 

 numbers over every part of the world, and Europe possessing 

 only about twenty of them out of the twelve hundred which our 

 collections are calculated to contain. Of these, according to 

 M. Jekel, who has specially studied the family, not more than 

 two hundred are published ; and there are consequently a num- 

 ber of new forms, only a few of which I have here attempted to 

 describe, and these principally derived from Mr. Wallace's re- 

 searches in the Indian Archipelago. Indeed the family may be 

 considered to have its head-quarters in those islands : in all 

 Mr. Wallace's collections, including those from New Guinea, 

 they formed, from the number both of species and individuals, a 

 very characteristic feature, and in this respect afforded a marked 

 contrast to collections from extra- tropical Australia. It is pro- 

 bable, however, that we shall hereafter find the northern or tro- 

 pical part of the Australian continent to assimilate more to the 

 opposite shores of New Guinea, and that the very distinctly 

 marked region extending from Java to the latter island will have 

 Ceylon, and perhaps a portion of Southern India, on the one 

 hand, with tropical Australia, and not New Guinea, on the other, 

 as outlying or transition provinces. 



As no attempt has yet been made to classify the family, which 

 contains at least three distinct types of form, I have thought it 

 best to avoid any remarks respecting the affinities or position of 

 the new genera here proposed*. It is, perhaps, as well also to 

 observe that the individuals of many Anthribidse vary much 

 more than is usual in regard to size, markings, and the relative 

 proportion of their parts, particularly of the rostrum and an- 

 tennas. 



* In order to condense as much as possible, I have generally omitted all 

 characters which belong to the Anthribidse as a family ; and even those 

 here given may perhaps hereafter be curtailed without disadvantage.
